7.3 Diagnosing Intermittent Problems

By analyzing the logged data, you can often identify the cause of intermittent issues that would be difficult to diagnose otherwise. For example, a faulty sensor may only malfunction under certain conditions, which would be evident in the logged data.

8. Performing Cylinder Power Tests with Blazt2 OBD2

A cylinder power test involves selectively disabling individual cylinders to identify misfires or other engine performance issues. The Blazt2 OBD2, combined with suitable software, makes this process straightforward.

8.1 Understanding Cylinder Power Tests

During a cylinder power test, each cylinder is temporarily disabled, and the engine’s RPM drop is observed. A significant drop in RPM when a particular cylinder is disabled indicates that the cylinder was contributing to the engine’s power. Conversely, little or no RPM drop suggests that the cylinder was not functioning correctly.

8.2 Step-by-Step Guide to Conducting a Cylinder Power Test

1. Connect Blazt2 OBD2: Ensure your Blazt2 OBD2 is connected to your vehicle and your computer, with the Nissan Datascan-II software running.
